A new texturized front area simulating a golf ball effect creates a better laminar flow. The overall weight reduction and a forward move of the center of gravity will create less fatigue at the neck area in an aero position allowing the rider to maintain the aero position for a longer period of time and prevents the low head drag. The helmet is also equipped with 2 huge front vent inlets and 3 large back vent outlets for maximum airflow without compromising aerodynamics.
